Buildings requiring an EPC
Posted by Mike Gordon on 22 July 2015 12:54 PM

An EPC is only required when a building is constructed, sold or rented out. For the

purposes of the regulations, a building is defined as

“a roofed construction having walls, for which energy is used to condition the indoor

climate, and a reference to a building includes a reference to part of a building which

has been designed or altered to be used separately”.

For a building to fall within the requirement for an EPC it must have a roof and walls and

use energy to condition the indoor climate.

Services considered to condition the indoor climate are the following fixed services:

heating, mechanical ventilation or air-conditioning. Although the provision of hot water

is a fixed building service, it does not condition the indoor environment and would not,

therefore, be a trigger for an EPC. The same argument applies to electric lighting.

Where a building is expected to have heating, mechanical ventilation or air conditioning

installed, it will require an EPC based on the assumed fit-out in accordance with the

requirements in Part L of the Building Regulations.

A building can be either the whole of a building or part of a building, where the part is

designed or altered to be used separately.

A part of a building designed or altered to be used separately is where the

accommodation is made or adapted for separate occupation. This could be indicated by

the accommodation having its own access, separate provision of heating and ventilation

or shared heating and ventilation, but with the ability by the occupier to independently

control those services. For a non-dwelling the part could be deemed to be separate

even if some facilities (i.e. kitchen and toilet facilities) were shared. An example might

be a unit in a shopping centre or a floor in an office building.
